Adjustable bed with wire grid mattress support

Abstract

An adjustable bed including a multi-section mattress frame mounted on a base frame. The mattress frame includes a head section and a lower section. The lower section may include an intermediate or seat section and a leg section. A mattress support is joined to the mattress frame. The mattress support includes a plurality of wire grids joined to the sections. Each grid includes a plurality of tandemly arranged, transversely extending, generally rectangular closed loops. End portions of the loops are axially aligned and joined to lateral or side portions of the mattress frame. A plurality of parallel, longitudinally or axially extending support wires are positioned on the loops. The support wires extend generally parallel to the lateral portions or sides of the mattress frame. Ends of the support wires may be downturned and joined to an end wire.

The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows: 
     
       1.

       2. A mattress frame as defined by claim 1 wherein said longitudinally extending support wires have downwardly turned ends. 
     
     
       3. A mattress frame as defined by claim 2 further including an end wire joined to said downwardly turned ends. 
     
     
       4. A mattress frame as defined by claim 3 wherein said end wire includes a base and upstanding legs, said downturned ends being joined to said base and wherein said frame further includes a transverse end wire joined to said support wires and to said upstanding legs of said end wire. 
     
     
       5. A mattress frame as defined by claim 4 wherein said wire loops are each generally rectangular in plan view with parallel end portions, said end portions of adjacent loops being axially aligned. 
     
     
       6. A mattress frame as defined by claim 5 further including an end wire loop having transversely extending, spaced parallel wire portions joined to curved end portions. 
     
     
       7. A mattress frame as defined by claim 1 wherein said wire loops are each generally rectangular in plan view with parallel end portions, said end portions of adjacent loops being axially aligned. 
     
     
       8. A mattress frame as defined by claim 7 further including an end wire loop having transversely extending, spaced parallel wire portions joined to curved end portions. 
     
     
       9. A mattress frame as defined by claim 1 wherein said grid work further includes a plurality of longitudinally extending spacer wires joined to said closed wire loops. 
     
     
       10. A mattress frame as defined by claim 9 wherein said grid work further includes a plurality of lower, transversely extending, spaced closed wire loops, said lower closed wire loops engaging said spacer wires and having end portions joined to said side sections. 
     
     
       11. A mattress frame as defined by claim 10 wherein said lower closed wire loops are staggered with respect to said plurality of spaced closed wire loops so as to be positioned between said plurality of closed wire loops when the grid work is viewed in plan. 
     
     
       12. A mattress frame as defined by claim 11 wherein said lower closed wire loops are generally rectangular in plan and said end portions thereof are axially aligned. 
     
     
       13. A mattress frame as defined by claim 12 wherein said longitudinally extending support wires have downwardly turned ends. 
     
     
       14. A mattress frame as defined by claim 13 further including a generally U-shaped end wire having a base joined to said downwardly turned ends and upstanding legs. 
     
     
       15. A mattress frame as defined by claim 14 further including a transverse end wire joined to said top surface wire and to said upstanding legs of said end wire. 
     
     
       16. An adjustable bed, comprising: a base frame;   a mattress frame including ahead section and a lower section operatively connected to said head section for relative angular movement, said sections each including spaced, generally parallel lateral portions;   mounting means on the base frame and connected to said mattress frame for mounting the mattress frame to the base frame and permitting the head section to be positioned and locked in different angular positions with respect to the base frame and said lower section;   a head section mattress support wire grid on said mattress frame head section; and   a lower section mattress support grid on said mattress frame lower section, each of said grids including:   a plurality of generally rectangular, closed loop members arranged in tandem, spaced, generally parallel relationship, said loop members each including end portions joined to said lateral portions of the respective mattress frame sections; and   a plurality of spaced, parallel support wires positioned on said loops and extending generally parallel to said lateral portions.   
     
     
       17. An adjustable bed as defined by claim 16 wherein support wires of said head section grid include lower ends which are bent downwardly and said lower section grid includes upper and lower ends which are bent downwardly. 
     
     
       18. An adjustable bed as defined by claim 17 wherein said head section grid further includes an end wire joined to said downturned ends. 
     
     
       19. An adjustable bed as defined by claim 18 wherein said head section grid further includes a transverse end wire joined to said support wire and to said end wire. 
     
     
       20. An adjustable bed as defined by claim 19 wherein each of said grids includes a plurality of longitudinally extending spacer wires joined to said closed loops and extending generally parallel to said support wires. 
     
     
       21. An adjustable bed as defined by claim 20 wherein each of said grids further includes a plurality of lower closed loops having transverse portions engaging said spacer wires and end portions joined to said lateral portions of one of the mattress frame sections. 
     
     
       22. An adjustable bed as defined by claim 21 wherein said lower closed loops in plan are positioned between said plurality of generally rectangular closed loops.
